Abstract
An anode element of a solid electrolytic capacitor and a method of fabricating the anode element are improved, so that the step of manufacturing the solid electrolytic capacitor is simplified, reliability is improved, and a withstand voltage of the solid electrolytic capacitor is increased. An anode element including a metal and a coating layer formed on a surface thereof, the coating layer being composed of a hydrated oxide shown as MO.yHO in chemical formula (1), where M represents a valve metal and x and y represent an integer or a decimal fraction from 1 to 6, a hydroxide shown as M(OH)in chemical formula (2), where M represents a valve metal and n represents an integer or a decimal fraction from 1 to 6, or a composite thereof, a method of manufacturing the anode element, and a solid electrolytic capacitor employing the anode element are provided.
